Description

面向多卡的网络管理 技术领域
本申请涉及通信领域，尤其涉及一种用于终端的网络管理方法和对应的终端。
背景技术
在目前的移动通信领域，出于对业务、流量、资费、个人需要等因素的考虑，越来越多终端支持插入和运行多张移动通信运营商的数据卡，通常为SIM卡。例如，两张数据卡隶属不同的运营商，一张卡是中国移动，另一张卡是中国联通。不同电信运营商的蜂窝网络覆盖存在一定的互补性，例如用户在高铁、地铁场景，中国移动的4G信号质量较差时，可能中国联通的4G信号质量较好。因此，如果能根据网络质量动态选择最佳的移动运营商网络接入，形成互补，就可以提高用户的通信体验。
随着通信协议的发展，多路传输控制协议(multipath transmission control protocol，MPTCP)/多路用户数据报协议(multipath user datagram protocal，MPUDP)协议允许UE(user equipment，用户设备)在两个不同的网络上平滑切换，保证了业务体验的连续。
在当前终端中，其通常设置了双卡双待(dual sim dual standby,DSDS)和双卡双通(dual sim dual active,DSDA)，当一张卡(称为卡1)处于2G/3G或者无网时，此时即便使用MP(multipath，多路)能力将数据业务切换到另一张卡(称为卡2)，卡1的搜网(LTE Cell Search)也会严重影响卡2的数据业务能力，表现为时延增大、并发数据量进一步降低、随时间进一步恶化。卡2的数据业务体验代表了当前用户的体验，其应该被保护，而如果卡1是用户根据流量因素设置的主卡，则卡1数据业务恢复的及时性又关系到使用成本和未来的用户体验。
发明内容
本申请实施例提供一种面向终端的网络管理机制，例如一种搜网调度方法，在保障当前用户数据业务体验的条件下，兼顾流量成本和未来的用户体验。“多卡”指的是多个用户识别模块，它们既可以是物理上分离的多张卡，也可以是例如一张数字用户识别卡(eSIM)上划分出的多个虚拟卡。
为了达到上述目的，本申请实施例采用如下技术方案：
第一方面，提供一种用于终端的网络管理方法，例如一种搜网调度方法，该终端具有至少两个用户识别模块，包括第一用户识别模块和第二用户识别模块，该网络管理方法包括：使终端在第二用户识别模块上运行第一数据业务，检测第一数据业务的网络占用率，基于该网络占用率确定第一用户识别模块的搜网方式。网络占用率包括例如网络使用频率和/或吞吐量。第一数据业务指的例如是包含在终端中设置的白名单中的业务。该白名单业务指的是该终端可以批准运行且时延敏感类的数据业务。时延敏感的标准可以是终端的用户自定义的，例如通过图形用户界面设置到终端中，也可以是终端出厂时预设的，也可以是在终端运行过程中从外部例如云端、服务器接收的规则，等等。该白名单可以作为配置文件设置在终端中，也可以作为代码集成到一段程序中，等等。应理解的是，搜网方式 并不意味着一定要执行搜网。可以根据场景需要而决定不搜网。检测第一数据业务的网络占用率的方式例如可以是根据第一数据业务特定时长里的网络占用率然后算出平均值。该特定时长例如是5s。
在一些可能的实现方式中，检测第一用户识别模块所处的网络类型，响应于检测结果，在网络类型是无网络的条件下，采用第一搜网方式对第一网络进行搜网，在网络类型是不同于第一网络的第二网络的条件下，采用第二搜网方式对第一网络进行搜网，该第二搜网方式不同于第一搜网方式。
在一些可能的实现方式中，第一网络是LTE网络或者比LTE更晚出现的通信网络，例如5G网络。
在一些可能的实现方式中，第二网络是2G网络。
在一些可能的实现方式中，第一搜网方式包括：在网络占用率低于网络占用率阈值的条件下，开启第一用户识别模块对第一网络的搜网。在一些可能的实现方式中，搜网直至第一时长，然后回到检测第一数据业务的网络占用率的步骤。第一时长例如为5s。
在一些可能的实现方式中，第一搜网方式包括：在网络占用率不低于网络占用率阈值的条件下，检查预设计时器是否超时，在计时器未超时的条件下，关闭第一用户识别模块对第一网络的搜网。在一些可能的实现方式中，在计时器超时的条件下，重置计时器并且开启第一用户识别模块对第一网络的搜网。在一些可能的实现方式中，关闭搜网直至第二时长，回到检测第一数据业务的网络占用率的步骤。第二时长例如是5s。在一些可能的实现方式中，搜网直至第一时长，回到检测第一数据业务的网络占用率的步骤。第一时长例如是5s。重置计时器指的是将计时器置零。对于“关闭第一用户识别模块对第一网络的搜网”，在此应理解为包含：第一用户识别模块当前在搜网，就将搜网停止；以及，第一用户识别模块当前未在搜网，就不开启搜网。对于开启搜网应理解为包含：第一用户识别模块当前在搜网，就不停止该搜网；以及，第一用户识别模块当前不在搜网，则启动其搜网。
在一些可能的实现方式中，第二搜网方式包括：在网络占用率低于网络占用率阈值的条件下，开启第一用户识别模块对第一网络的搜网。在一些可能的实现方式中，搜网直至第三时长，回到检测第一数据业务的网络占用率的步骤。第三时长例如是5s。

在一些可能的实现方式中，网络管理方法还包括：判断第一数据业务是否关闭或切换到后台，响应于第一数据业务关闭或来切换到后台，或者终端锁屏，开启第一用户识别模块对第一网络的搜网。在一些可能的实现方式中，响应于第一数据业务关闭或切换到后台，或者终端锁屏，去激活第二用户识别模块上运行的第一数据业务。在一些可能的实现方式中，在第一数据业务关闭或来切换到后台后，响应于第二数据业务被设置到前台，在第一用户识别模块上建立第一数据通路以运行该切换到前台的第一数据业务。应理解的是该被设置到前台的第二数据业务与被关闭或切换到后台的第一数据业务可以相同也可以不同。第一数据业务和第二数据业务指的例如是包含在终端中设置的白名单中的业务。该白名单业务指的是该终端可以批准运行且时延敏感类的数据业务。时延敏感的标准可以是终端的用户自定义的，例如通过图形用户界面设置到终端中，也可以是终端出厂时预设的，也可以是在终端运行过程中从外部例如云端、服务器接收的规则，等等，本申请对设置方式不 做限定。该白名单可以作为配置文件设置在终端中，也可以作为代码集成到一段程序中，本申请对白名单的存储和实施方式不做限定。在第一数据业务关闭或切换到后台或者终端锁屏后，可以开启第一用户识别模块的搜网和/或去激活第二用户识别模块的第一数据业务，然后等到第二数据业务被设置到前台，在第一用户识别模块建立第一数据通路。也可以在第一数据业务关闭或切换到后台或者终端锁屏后，不做第一用户识别模块的搜网也不去激活第二用户识别模块的第一数据业务，仍然等到第二数据业务被设置到前台，在第一用户识别模块建立第一数据通路。换言之，在第一数据业务关闭或切换到后台或者终端锁屏后，已经没有重要业务在当前需要网络，所以可以不搜网就利用空挡切换到第一用户识别模块上试一试业务体验和链路质量是不是能够满足预设阈值。另外，在第一数据业务关闭或切到后台或者终端锁屏的条件下，在该第二用户识别模块上去激活该第一数据业务也不是必要的，MPTCP/MPUDP协议允许终端在两个不同网络上平滑切换，因此通过在第一用户识别模块上建立第一数据通路可以将第一数据业务平滑转移到第一用户识别模块上，从而当第一数据业务被切回前台或重新激活时从用户体验角度来讲还是平滑连续地运行的。
在一些可能的实现方式中，网络管理方法还包括：检查是否有最近第五时长内更新的第一数据业务的业务体验数据可用。第五时长例如是1min，则最近第五时长指的是从做该检查的时刻起倒推1min。在一些可能的实现方式中，在检查是否有最近第五时长内更新的业务体验数据可用前先判断网络占用率是否低于网络占用率阈值，在网络占用率是不低于网络占用率阈值的条件下检查是否有最近第五时长内更新的业务体验数据可用。在一些可能的实现方式中，网络占用率不低于网络占用率阈值指的是网络使用频率不低于网络使用频率阈值并且吞吐量不低于吞吐量阈值。

在一些可能的实现方式中，响应于第一用户识别模块的链路质量高于第二用户识别模 块的链路质量，开启第一用户识别模块对第一网络的搜网。在一些可能的实现方式中，响应于第一用户识别模块的链路质量高于第二用户识别模块的链路质量，去激活第二用户识别模块上运行的第一数据业务。在一些可能的实现方式中，响应于第一用户识别模块的链路质量高于第二用户识别模块的链路质量，在第一用户识别模块上建立第一数据通路并且将第一数据业务转移到第一用户识别模块上。在一些可能的实现方式中，第一用户识别模块的链路质量是存储在终端中的，例如是切换到第二用户识别模块之前最后记录的第一用户识别模块的链路质量。在第一用户识别模块的链路质量高于第二用户识别模块的链路质量的条件下，可以开启第一用户识别模块的搜网和/或在第二用户识别模块上去激活第一数据业务，然后切换到第一用户识别模块建立第一数据通路。也可以不做第一用户识别模块的搜网，也不在第二用户识别模块上去激活第一数据业务，直接切到第一用户识别模块。因为此时第二用户识别模块的用户体验已然不满足阈值，第一用户识别模块在切到第二用户识别模块之前的链路质量又更高，所以即使先不对第一用户识别模块进行搜网，也可以切回第一用户识别模块尝试一下体验会不会优于第二用户识别模块。而由于MPTCP/MPUDP协议允许平滑切换网络，即使先不在第二用户识别模块上去激活第一数据业务，也预期该第一数据业务可以平滑切换到第一用户识别模块上而不会出现错乱。

具体实施方式
为了便于理解，示例的给出了部分与本申请实施例相关概念的说明以供参考。如下所示：
用户识别模块，其安全存储国际移动用户识别码(International Mobile Subscriber Identification Number，IMSI)和相关秘钥，用于移动终端上用户在移动通信网络中的身份识别以及鉴权。用户识别模块可以由集成电路构成，也可以由软件构成。用户识别模块例如实现为SIM卡。
搜网，指的是搜索适合的无线信号覆盖区域，以供终端进行数据业务。如果目标无线信号覆盖区域是LTE网络中的，则搜网指的是UE要接入LTE网络而必须经过的小区搜索过程(cell search procedure)，目的是找到适合驻留的小区。如果目标无线信号覆盖区域是5G网络中的，搜网指的也是找到适合驻留的小区。
往返时延(round-trip time，RTT)，指的是从发送端发送数据开始，到发送端收到来自接收端的确认(接收端收到数据后便立即发送确认)，总共经历的时延。
信噪比(signal-to-noise ratio，SNR)，定义为信号功率与噪声功率的比。
参考信号接收功率(reference signal receiving power，RSRP)，定义为考虑的测量频率带宽上承载参考信号的资源元素(RE)上的接收功率(以瓦为单位)的线性平均值。是LTE网络中可以代表无线信号强度的关键参数。
用户识别卡(subscriber identity module，SIM)，主要用于存储用户身份识别数据、短信数据和电话号码的智能卡。
数据通路，指的是移动终端与基站之间的数据报文传输连接。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。其中，在本申请实施例的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；本文中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，在本申请实施例的描述中，“多个”是指两个或多于两个。
以下，术语“第一”、“第二”等仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”等的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
本申请实施例的技术方案适用于任何可以被实现为具有无线通信功能的便携式通信终端，包括：便携式终端、移动终端、通信终端、便携式通信终端、便携式移动终端、显示设备等等。对应于市场上的产品，终端可以对应于智能电话、便携式电话、游戏机、电视、显示单元、用于车辆的抬头显示单元、笔记本计算机、膝上型计算机、平板个人计算机(PC)、个人媒体播放器(PMP)器、个人数字助理(PDA)等等。
终端可以与诸如服务器等的外部电子设备通信，或者通过与外部电子设备交互工作来执行操作。网络可以是移动或蜂窝通信网络。
图1示出了本申请实施例提供的网络管理方法的流程图。
网络管理方法100用于终端的搜网策略制定，例如用于智能手机。该终端上具有例如两个用户识别模块，例如两张SIM卡，以下称为卡1和卡2。在一些实施例中，该终端能够支持两种制式，因此卡1和卡2可以由不同的移动通信运营商运营。在一些实施方式中，多路技术可以应用于双卡环境，业务首先使用其中一张卡，建立第一条MPTCP数据通路(FirstFlow)，当该卡的业务体验不满足业务需要时，可以动态建立第二条MPTCP数据通路(SecondFlow)，从而将业务的数据流量平滑切换到另一张卡或两张卡同时冗余发送数据，以充分利用两个运营商的网络能力，保证最佳的业务通信体验。
为了运行卡1和卡2，终端可以具有一套射频装置以分时多工的方式支持卡1和卡2的数据业务，也可以具有两套分别专用于卡1和卡2的射频装置。SIM卡可以是插入终端卡槽中的两张物理上分离的实体SIM卡，也可以是集成到终端内部的eSIM卡，则两个用户识别模块可以是在该eSIM卡上从逻辑上划分出的两张卡。该终端上也可以具有多于两张SIM卡。
在一些实施例中，卡1上的流量合同使得运行数据业务时在资费上更为经济，因此终端用户将其设置为主卡，即在卡1能够驻留在LTE网络或更新代网络、例如5G网络时优先使用卡1运行数据业务。该设置例如可以通过图形用户界面操作。相应地，将卡2设置为副卡，在卡1的网络质量不能够支持达到阈值的业务体验时手动或自动切换到卡2，以 将卡1上的数据业务通过MPTCP/MPUDP协议平滑切换到卡2上以保证用户的不间断业务体验，或者是在卡2上运行新的数据业务。
然而，如上面所说，卡2可能由于流量资费、个人需求等原因而不适合持久运行数据业务。因此在卡2运行数据业务时终端会进行卡1的搜网，例如搜索LTE网络中适合驻留的小区，未来5G网络中也是搜索适合驻留的5G网络区域，以便在找到时及时切回卡1运行数据业务。然而在使用卡2运行数据业务时，卡2代表了当前用户体验，卡1的搜网会抢占有限的空口资源，进而影响卡2上的体验。例如当卡2上正在运行时延敏感类业务时，卡1的搜网会引起卡2体验的明显劣化。例如用户在玩网络游戏时，150ms以上的时延会使得用户体验到操作响应对于手对鼠标的操作而言有所迟滞，语音/视频通话时，300ms以上的时延使得用户体验到通话对象对自己语音的响应有迟缓。
图1中示出的本发明实施例提供的网络管理方法根据终端的不同运行场景来提供不同的搜网方式，以在保障用户当前体验的条件下有效搜网。步骤110描述了当前正在用卡2运行目标数据业务。目标数据业务可以是时延敏感类业务，例如打电子游戏。在步骤120中检测电子游戏的网络占用率。网络占用率在本申请中指的是目标数据业务对网络的占用情况，包括频率和带宽。在本实施例中检测方式是跟踪最近5s的网络占用率，然后取时间上的平均值。在另一些实施例中，也可以采用其他检测方法，比如检测当前瞬时的网络占用率，检测特定时刻的网络占用率，检测更长或更短时段的平均网络占用率等等。在本实施例中，网络占用率包括网络使用频率和吞吐量。网络使用频率指的是特定时段里面数据包的传输频率，计算方式例如，5s内，如果每秒都有发包，网络使用频率是100％，如果只有4s发包，网络使用频率是4/5即80％。吞吐量指的是单位时间中发送的数据量大小，例如单位时间中发送的比特数。
承接于步骤120的是并行的步骤130A、130B和130C。在步骤130A中，根据卡1当前的网络类型来进行相应的网络管理。在步骤130B中，根据卡2上目标数据业务的用户体验来进行网络管理。在步骤130C中，响应于目标数据业务离开前台而进行网络管理。目标数据业务离开前台的情况包括目标数据业务切换到后台，目标数据业务关闭和终端锁屏。
图2是图1中步骤130A的详细描述，即如何根据卡1当前的网络类型来进行相应的搜网调度。
在步骤201中检测卡1当前所处的网络类型。当卡1处于可以执行基本业务、例如接打电话，但是非目标网络时，在卡2上目标数据业务网络占用率较低的间隙搜网。在本实施例中，卡1目前处于2G网络，搜网的目标是4G网络。本领域技术人员可以理解的是，以此类推，例如在5G网络时代，可能卡1目前处于4G，而搜网的目标是5G网络。具体地，判断图1中步骤120中检测出的网络占用率是否满足预设的网络占用率阈值。在本实施例中仍以游戏作为目标数据业务，首先通过网络使用频率得出数据包发送的稀疏度，以判断目标数据业务是否在运行和运行的状况。
如果数据包较为稀疏，例如5s中只有两次发包，如图3A所示，可以认为业务并不需要密集数据流，此时即使短时搜网也不会影响业务的进行和用户对业务的体验。当前游戏业务例如是玩家(即用户)在备战室聊天等待被匹配的场景。玩家1询问玩家2是否已到达同一备战室，玩家2几秒钟后回复说已到达。在该场景下，网络占用率不满足预设网络占用率阈值，例如网络使用频率不满足预设的80％的阈值，吞吐量也由于文字聊天单位时 间内数据量较小而不满足预设阈值。则在该场景下开启卡1的搜网。在本实施例中，在图2的步骤202开启搜网直至特定时长，例如5s，然后回到图1中的步骤120，即再次采集最近的网络占用率。在另一些实施方式中，通话中通话各方沉默或寡言的场景中，虽然网络使用率较高但吞吐量小，也会触发卡1的搜网。
如果数据较为密集，例如5s中每秒都有发包，如图3B所示，例如此场景是游戏已经开始，玩家已进入紧张的作战状态。在该场景下，网络使用频率是100％，超过预设阈值，吞吐量也由于密集而规则的数据流而超过预设阈值，从而使得网络占用率不低于预设的网络占用率阈值。在这种情况下，在本实施例中认为如果让卡1搜网会明显阻碍游戏业务的平滑进行，和造成玩家业务体验的明显劣化。例如，如果卡1搜网造成卡2上运行的游戏时延200ms以上，玩家会感觉到卡顿，150ms以上感觉到不跟手，即鼠标或键盘操作后游戏的响应不是即时的，有所迟滞。例如鼠标拖动一个物体时物体因移动速度落后于光标而显得粘滞。因此在图2的步骤203中关闭主卡搜网。在本实施例中关闭卡1搜网直至特定时长，例如5s，然后回到图1中的步骤120，即再次检测最近的网络占用率。在另一些实施例中，语音通话中通话各方在激辩，则网络使用频率和吞吐量都超过阈值，也会触发关闭卡1搜网。
应理解的是，关闭主卡搜网的含义包括了：如果现在主卡本来就在搜网，就停止搜网；如果现在主卡没有在搜网，就不启动其搜网。开启搜网也应被理解为：如果现在主卡没在搜网，就开始搜网；如果现在主卡已经在搜网，就不停止其搜网。因为要考虑到本实施例中有三条并行的判断线路在执行搜网调度，有可能在按照卡1网络类型搜网中未开启卡1搜网时，其已经在其他线路中被开启，同样，在按照卡1网络类型搜网中未走到关闭卡1搜网这一步时，它已经在其他线路中被关闭。
回到图2，如果卡1目前无网络，则除了寻找卡2上目标数据业务网络占用率低的间隙进行卡1搜网之外，还设定定时器周期搜网。具体地，如果图1中步骤120获取的网络占用率低于预设的网络占用率阈值，即例如图3A所示的备战场景中(只是此时卡1为无网络)，在图2的步骤204中开启卡1搜网。在本实施例中，开启卡1搜网直至特定时长，例如5s，就回到图1中步骤120，即再次检测网络占用率。如果图1中步骤120获取的网络占用率不低于预设的网络占用率阈值，即例如图3B所示的作战场景中(只是此时卡1为无网络)，则在图2的步骤205中检测预设计时器是否超时，如果计时器超时了，则在步骤206中重置计时器，即将计时器清零，并且在步骤204中开启卡1搜网。仍然可以搜网直至特定时长，例如5s，然后回到图1中步骤120。如果计时器没有超时，则在步骤207中关闭卡1搜网。例如可以关闭直至特定时长，例如5s，就回到图1中步骤120，即再次检测网络占用率。从而保证了从卡2上目标数据业务中找不到网络占用率较低的搜网间隙时仍能保证搜网，以避免卡1较长时间断网而错过重要业务。
图4是图1中步骤130B的详细描述，即根据卡2上目标数据业务的业务体验来进行搜网调度。首先在步骤401中判断步骤120(图4中的步骤120即为图1中的步骤120)中获取的网络占用率是否不低于网络占用率阈值，据此判断目标数据业务是否处在活跃运行的状态。
如果网络占用率低于阈值，例如数据包过于稀疏，则目标数据业务现在不活跃，例如在图3A的备战场景中，或者语音通话中通话各方沉默的场景中，则在该实施例中认为此时去采集的业务体验数据和基于该业务体验数据所做的判断是难以代表用户真实体验的， 也即不适合用步骤130B这条线做搜网调度，则回到步骤120，即再次检测网络占用率。在另一些实施例中，认为目标数据业务只要网络占用率不为0，即还在运行就可以根据业务体验来进行搜网调度，那么也可以将判断网络占用率是否不低于网络占用率阈值的步骤省去，从步骤120B直接到判断业务体验和链路质量是否满足阈值的步骤。
如果步骤120中获取的网络占用率不低于阈值，则在步骤402中检查是否有最近特定时长中是否有卡2上目标数据业务的业务体验数据可用。特定时长例如是1min，则最近特定时长指的是从做该检查的时刻起回溯1min。如果1分钟内业务数据都没得到更新，即没有数据包的传送，认为没有可以作为后续判断基础的业务体验数据。如果有业务体验数据可用，在步骤403A中基于该业务体验数据检查业务体验是否不低于业务体验阈值。相反，如果没有业务体验数据可用，在步骤403B中检查卡2的链路质量是否不低于链路质量阈值。业务体验可以用参数RTT来代表。RTT的阈值设定取决于目标数据业务的类型，如果是游戏业务，可以将阈值设为例如150ms，则业务体验不低于业务体验阈值至的是业务的RTT不高于150ms。链路质量在不同的网络中可以用不同的参数来代表。在4G网络中可以用RSRP来代表。在上述检测卡2上目标数据业务的业务体验和卡2的链路质量是否满足阈值的步骤中，例如RSRP不低于-115dBm认为链路质量满足阈值。在2G网络中，可以用SNR代表链路质量。
响应于业务体验不低于业务体验阈值，或者链路质量不低于链路质量阈值，回到步骤402再次检查是否有最近特定时长中是否有卡2上目标数据业务的业务体验数据可用。
响应于业务体验低于业务体验阈值，或者链路质量低于链路质量阈值，则在步骤404中将卡2的链路质量与卡1的链路质量相比较。在本实施例中，卡1的链路质量是存储在终端中的数据，代表的是最近一次从卡1切换到卡2时记录的卡1的链路质量。在另一些实施例中，卡1的链路质量也可以是当前测量的数据，等等。如果卡1的链路质量比卡2的链路质量高，则在步骤405中切换到卡1，在卡1上建立数据通路和运行数据业务。根据MPTCP/MPUDP协议，允许数据业务在两张SIM卡之间平滑切换。在一些实施例中，在切回卡1之前，还可以开启卡1搜网，和/或去激活卡2上的目标数据业务。
图5是对图1中步骤130C的详细描述。当在步骤501中检测到目标数据业务关闭或切换到后台，或者终端锁屏时，在步骤502开启主卡搜网。此时用户体验不到目标数据业务，所以在该场景下搜网不会影响用户体验。但是在该场景下的搜网不是必须的。还可以在步骤503中去激活副卡数据业务，但该步骤也不是必须的。如果在该场景下有白名单上的数据业务到达前台，则可以切换到卡1，在卡1上建立数据通路运行数据业务。因为在该实施例中如在描述图1时所设的前提条件，即卡1是主卡，或者流量卡，则在卡2不以影响用户体验的方式运行数据业务的条件下，可以切回卡1以尝试是否可以用卡1以满足用户体验的方式运行数据业务。以Android操作系统为例，可以通过调用foreground.get()函数检测数据业务是否在前台，返回结果为true，即为真，表示在前台，返回结果为false，即为假，表示在后台。
图6示出了将目标数据业务迁移到卡2上运行的方法。在该方法600中，在终端启动后，如果有白名单业务到前台，即步骤601将其作为目标数据业务，在步骤602卡1上建立第一条数据通路以运行该目标数据业务。该白名单业务指的是该终端可以批准运行且时延敏感类的数据业务。时延敏感的标准可以是终端的用户自定义的，例如通过图形用户界面设置到终端中，也可以是终端出厂时预设的，也可以是在终端运行过程中从外部例如云 端、服务器接收的规则，等等。该白名单可以作为配置文件设置在终端中，也可以作为代码集成到一段程序中，等等。
接下来在步骤603中检查是否有最近特定时长中是否有卡1上目标数据业务的业务体验数据可用。特定时长例如是1min，则最近特定时长指的是从做该检查的时刻起回溯1min。如果1分钟内业务数据都没得到更新，即没有数据包的传送，认为没有可以作为后续判断基础的业务体验数据。如果有业务体验数据可用，在步骤604A中基于该业务体验数据检查业务体验是否不低于业务体验阈值。相反，如果没有业务体验数据可用，在步骤604B中检查卡1的链路质量是否不低于链路质量阈值。业务体验可以用参数RTT来代表。RTT的阈值设定取决于目标数据业务的类型，如果是游戏业务，可以将阈值设为例如150ms，则业务体验不低于业务体验阈值至的是业务的RTT不高于150ms。链路质量在不同的网络中可以用不同的参数来代表。在4G网络中可以用RSRP来代表。在上述检测卡2上目标数据业务的业务体验和卡2的链路质量是否满足阈值的步骤中，因为在此对链路质量的判断是用于后续判断是否切到卡2，可以将链路质量阈值设置得比图4中判断链路质量以决定是否继续在卡2上运行业务时高一些，例如设置为-105dBm。也可以较为粗略地根据终端屏幕上显示的信号强度格数来判断，如果5格中有3格是亮的认为链路质量满足阈值。在2G网络中，可以用SNR代表链路质量。
在步骤605中判断是否低于老化时间，老化时间指的是上次从卡1切到卡2开始计时，到步骤605的时间，具体数值可以由终端或用户设置。在本实施例中将老化时间设置为2min。在另一些实施例中，老化时间可以为其他数值，例如1min。如果低于老化时间，回到检查是否有最近特定时长中是否有卡1上目标数据业务的业务体验数据可用的步骤603。从而避免了主卡与副卡之间的频繁切换，也称为“防乒乓”。如果不低于老化时间，在步骤606中，在卡2上建立第二条数据通路。在步骤607中，将目标数据业务迁移到卡2上。在步骤608中，关闭主卡搜网。
图7示出了本发明实施例提供的网络管理方法的纵览。其各个部分和步骤已基于图1-6进行了描述，在此仅简单描述。白名单业务到前台后，卡1建立数据通路以运行该业务，后面将其称作目标数据业务。在例如最近1min有业务体验数据的条件下，判断业务体验是否满足阈值，没有业务体验数据则判断链路质量是否满足阈值。在业务体验或链路质量满足阈值的条件下返回再次检测最近1min有没有业务体验数据可用。如果业务体验或链路质量不满足阈值，则切到卡2建立数据通路，并且将卡1上目标业务迁移到卡2上继续运行。将卡1搜网关闭。采集卡2上目标业务例如最近5s的网络占用率。接下来是三条并行的搜网调度判断逻辑。第一条按照卡1当前的网络类型来判断，具体方法参考图2及其描述。第二条按照卡2当前业务体验来判断，具体方法参考图4及其描述。第三条按照目标业务是否切到后天或关闭以及终端是否锁屏来判断，具体方法参考图5及其描述。
以玩电子游戏为例，玩家1在手机上打开游戏app，则游戏作为白名单业务到前台成为了目标数据业务。玩家1手机上电信的包月无限流量卡被设置成主卡。先在主卡上建立第一数据通路运行游戏。检查是否有最近1min内更新的业务体验数据可用，有的话检查其是否满足阈值。没有业务体验数据可用则检查链路质量是否满足阈值。如果业务体验或链路质量满足阈值，则再次检查是否有最近1min内更新的业务体验数据可用。如果如果业务体验或链路质量不满足阈值，则检查距上次切到副卡的时间有没有达到预设的老化时间1min。达不到就返回检查是否有最近1min内更新的业务体验数据可用的步骤。则在手 机的副卡、例如为包含每月1G流量的联通卡上建立数据业务，将游戏利用多路技术平滑迁移到副卡上。接下来采集副卡上游戏5s内的网络占用率，并进行三路并行搜网调度分析。
第一路，检查主卡现在是否处在2G或无网。如果是2G，检查网络占用率是否达到阈值，如果达到了，说明游戏正在战斗状态，此时进行主卡搜网会负面影响玩家1的游戏体验，例如卡顿。因此再次采集网络占用率。相反，如果网络占用率达不到阈值，说明游戏正在备战状态，此时偷时隙进行主卡搜网也不会影响玩家1的体验，因此搜网5s，搜到了4G就切回主卡，搜不到就返回采集副卡上游戏5s内的网络占用率的步骤。如果上面的检查结果是主卡处在无网，则即使副卡上游戏的网络占用率达到了阈值，还要检查预设的计时器是否溢出，如果溢出，仍要搜网5s。
第二路，检查副卡上游戏的业务体验是否满足阈值。在此之前先检查网络占用率是否达到阈值，如果结果是否定的，说明现在业务没有密集进行那么业务体验数据也是不值得考察的，则回到采集副卡上游戏5s内的网络占用率的步骤。如果网络占用率达到了阈值，再看是否有最近1min内更新的业务体验数据可用，没有就再次检查。如果有业务体验数据可用，则判断业务体验是否满足阈值，满足就再次检查是否有业务体验数据可用，不满足则切回主卡，将游戏平滑移回卡1。
第三路，如果游戏离开前台，例如切到后台，关闭，或者手机锁屏。则可以在有白名单业务到前台的条件下切回主卡，该白名单业务可以是同一游戏，也可以是其他业务，例如淘宝。或者，在游戏离开前台后也可以先主卡搜网和/或在副卡上去激活游戏，再等到有白名单业务到前台后切回主卡。

本申请实施例的基本思想是，在数据业务由于主卡体验不佳切换到副卡时，且主卡掉2G/3G或无网时，并非立即启动主卡搜网，而是根据用户当前的业务流量特征和用户场景，动态控制搜网时机。一方面，尽快搜网会最大可能性尽快恢复用户主卡的被叫呼通能力，另一方面频繁持续搜网会中断业务流量，造成体验中断。所以本发明要解决的核心技术问题是，如何刻画业务流量的特征和用户场景，在满足条件时搜网，不满足条件时停止搜网，从而在用户体验和尽快搜网之间达成一个权衡。
举一个例子来阐述：用户乘车移动到地点A附近，由于主卡的运营商在A附近没有足够的基础设施能力，此时主卡的信号质量不佳掉2G，切换到副卡。情况1：主卡连续搜网1分钟未能成功连接运营商A的网络，但由于搜网过程，导致副卡也无法发送数据业务，这种情况下，用户全程无法上网；情况2：系统探测到用户此时在密集使用数据业务(发送微信信息)，暂时停止搜网，而后在微信发送之后，用户锁屏，此时启动搜网，全程用户体验是网络畅通。

所属领域的技术人员可以清楚地了解到，为描述的方便和简洁，上述描述的系统、装 置和单元的具体工作过程，可以参考前述方法实施例中的对应过程，在此不再赘述。
在本申请所提供的几个实施例中，应该理解到，所揭露的系统、装置和方法，可以通过其它的方式实现。例如，以上所描述的装置实施例仅仅是示意性的，例如，所述单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如多个单元或组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。另一点，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口，装置或单元的间接耦合或通信连接，可以是电性，机械或其它的形式。
所述作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部单元来实现本实施例方案的目的。
另外，在本申请各个实施例中的各功能单元可以集成在一个处理单元中，也可以是各个单元单独物理存在，也可以两个或两个以上单元集成在一个单元中。
所述功能如果以软件功能单元的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分或者该技术方案的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质中，包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)执行本申请各个实施例所述方法的全部或部分步骤。而前述的存储介质包括：U盘、移动硬盘、只读存储器、随机存取存储器、磁碟或者光盘等各种可以存储程序代码的介质。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应所述以权利要求的保护范围为准。
